How to install an SSL certificate on Microsoft IIS 5 & 6

On 20/08/2015 By Thomas Huther

1. Once issued by the publisher, your certificate is available on your HTTPCS interface. Download the .zip file in the "My SSL certificates" section. Copy and paste it into a text file (for example OriginalCert.txt) using Notepad including delimiters -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----. Do not use a text editor like Word or LibreOffice as they can corrupt the file. Remove empty lines from the file. Save the text file with .crt extension.

2. Open Internet Information Services Manager.

3. Click on Internet Information Services then expand the tab of the web server to secure.

4. In the "Directory Security" tab, Click on "Server Certificate" in the "Secure Communications" section.

5. Click on Next. Then select the 1ast option and click on Next.

6. Add your certificate's path and name including the .crt extension (step 1). Check the certificate information, click on Next, then on Finish.
